i need complete solution not just answer

Answer 1

Step-by-step explanation:

There are 45 - 25 = 20 girls in the class.

so, the probability that a randomly selected students is a girl is 20/45 = 4/9.

So, your answer wil be 4/9

Answer 2

Number of students in a class: 45 students

Number of girls: 20

First we will subtract 20 from 45

45 - 20 = 25

This will give us the number of boys in the class

25/45 = 5/9

5/9 is the correct answer
